Kevin Luo's top hitter fantasy baseball prospects to stash for Week 4 (2025). His MLB prospects to pick up and stash on your bench and N/A spots in redraft leagues.
After last week's deadline for prospects to be called up to be eligible for a PPI pick, the next big benchmark period for prospect call-ups could be the Super Two cutoff in early May. Hopefully, we won't have to wait that long to get some more exciting call-ups.
We had three pretty big hitter call-ups this week in Edgar Quero, Caleb Durbin, and Luke Keaschall, but there are still plenty of exciting prospects on the precipice of the majors.
Let's take a look at a few top ones to stash for this week.

Nick Kurtz, 1B, Athletics
We're at Michael Scott during "The Office" fire drill, with "Oh my god, it's happening." Nick Kurtz is potentially getting the call to the majors.
Brent Rooker has played a few games in the outfield over the last week, and the A's have said they may experiment with Tyler Soderstrom playing some third base. They're clearly opening up as many avenues to have these two and Kurtz in the lineup every day once Kurtz gets the call.
Kurtz's rampage against Triple-A pitching will likely continue until he's in the majors, as he has a 176 wRC+ and seven homers, which leads all of the minor leagues.

I compare writing about Kurtz in my weekly top hitting prospects to stash article to the cats I volunteer with. I tell them every week that I will see them next week, but I hope I don't because that means they got adopted. I will see you in this article next week, Nick Kurtz, unless the A's call you up.
The crop of starting first basemen is looking stronger with the emergence of young sluggers like Ben Rice and Soderstrom, but Kurtz could be a top-10 first baseman for the rest of the season once he's in the majors with strong four-category production.
Roman Anthony, OF, Boston Red Sox
Similar to Kurtz, the clock should be ticking on the Red Sox calling Roman Anthony up to the majors. Anthony is arguably the top prospect in baseball, and the Red Sox offense has been sputtering as of late.
The Red Sox have scored two or fewer runs seven times over the last couple of weeks, including twice in a series loss to the White Sox. The team needs a jolt, and Anthony would provide that jolt.
To start the year at Triple-A, Anthony is doing what he's done at every stage of his minor league career: hitting. While often being young for his respective level, he posted a 143 wRC+ in 2023, a 149 wRC+ in 2024, and currently has a 161 wRC+ this season (before his two home run performances on Thursday).
Anthony has an incredibly advanced approach at the plate, constantly posting high walk rates (22 percent this season) and keeping his strikeout rate in check. He pairs that approach with elite quality of contact metrics.

Unlike the A's, the Red Sox don't seem to be creating a clear path for Anthony to get into their lineup. Jarren Duran is coming off a monster breakout season. Wilyer Abreu has been one of their best hitters so far this season.
Although it's apparent the Red Sox value his defensive impact, it's getting harder to justify Ceddanne Rafaela continuing to have an everyday role with a 49 wRC+ and a prospect of Anthony's caliber waiting for his opportunity.
When Anthony gets the call, he'll be a worthwhile starting outfielder in almost all formats, providing solid five-category production for roto leagues and an advanced approach that should translate well in points leagues.
Coby Mayo, 3B, Baltimore Orioles
Mayo has been one of the best power-hitting prospects in baseball over the last few years. In 2023, he hit 29 HR with a 156 wRC+ across Double-A and Triple-A. In 2024, he hit 22 home runs with a 135 wRC+ in Triple-A while also spending time in the majors.
That time in the majors was, unfortunately, an utter disaster for Mayo. In 46 PA, he had a -6 wRC+ and struck out 47.8 percent of the time. However, he's not the first Orioles prospect to struggle in their first taste of the majors. Jackson Holliday and Colton Cowser both notably struggled in their first time in Baltimore.
After not winning a job out of camp, the clock might be ticking for Mayo to get another chance in the majors as he has a 138 wRC+ this season in Triple-A and has homered three times in the last week.

The question is: Will the Orioles give Mayo another chance, or will another team?
The Orioles have a logjam of position players across their entire big league lineup. However, they have quite a few regulars off to slow starts. Jordan Westburg, Ryan Mountcastle, Holliday, and Heston Kjerstad all have wRC+ below 100. Could Mayo unseat any of them?
The likelier path to the majors for Mayo might be on another team. The Orioles rotation right now is in shambles. After losing Corbin Burnes in free agency this offseason, their rotation additions were Charlie Morton and Tomoyuki Sugano.
These two were supposed to be at the back of the rotation, but are now "anchoring" their rotation. Zach Eflin (lat) is on the IL, Kyle Bradish (elbow) is recovering from Tommy John surgery, and now Grayson Rodriguez, who has been out, is undergoing an MRI after experiencing shoulder soreness.
The Orioles need reinforcements for their rotation, and they need them soon if they have aspirations of making the postseason. The Orioles and Marlins have made a trade before, sending a starter to Baltimore for blocked hitting prospects. Could Mayo be the centerpiece of a Sandy Alcantara trade?
Wherever Mayo is playing, when he gets back to the big leagues, he'll provide good power and will have a lot of value if he can keep the strikeouts in check.
Agustin Ramirez, C, Miami Marlins
I had combined Agustin Ramirez with Kyle Teel in my first hitting prospects to stash article of the season, as they both seemed like high-upside catchers with a solid amount of opportunity in bad offenses.
The White Sox just called up Edgar Quero, an exciting young catcher in his own right, so Teel may have to wait longer for his opportunity. As a result, Ramirez will be featured by himself.
When Miami's starting catcher, Nick Fortes (oblique), went on the IL, there was some speculation that Ramirez might get the call right then and there.
However, it has turned to Rule 5 selection Liam Hicks and journeyman (the kindest way I could describe his professional baseball career) Rob Brantly to handle the catching duties.
Frankly, it feels like the Marlins are wasting everyone's time with this decision. As a Rule 5 selection, it makes sense the Marlins want to see what they have with Hicks but he could surely still be the backup for Ramirez, who had plenty of runway to be a primary catcher until Fortes returned.
Ramirez is a solid all-around hitter as he had a 130 wRC+ last season across Double-A and Triple-A, but what makes him especially exciting for fantasy is that he brings both power and speed to the catching position. He hit 25 HR and had 22 SB in the minors last season.
A catcher rarely has this much base-stealing prowess, so it can be quite a hot commodity for fantasy. The upside of a catcher who can provide Ramirez's power-speed blend is worth stashing if you went cheap at catcher, and especially if you play in two-catcher leagues.
When he gets the call, Ramirez has starting catcher upside and could have a J.T. Realmuto-lite fantasy profile.
Jordan Lawlar, SS, Arizona Diamondbacks
The closer Ketel Marte gets to returning to the Diamondbacks lineup, the less confident I am in including Lawlar on this list, so this may be his last week included in the write-up for a while.
While the permanent spot for Lawlar on the Diamondbacks is extremely unclear, a solid everyday role for a few weeks seemed like an excellent opportunity for him to prove his worth in the majors.
Instead, the Diamondbacks have been playing Garrett Hampson and Tim Tawa in Marte's spot at second base. To their credit, both have done a serviceable job, but neither offers the upside of Lawlar, and neither is expected to be in the Diamondbacks' long-term plans like Lawlar is.
Since Marte's injury (hamstring), Lawlar has been playing mostly second base at Triple-A, and he has been raking. He just had his third straight start with a homer. He has a 132 wRC+ (before Thursday's homer) and had a 156 wRC+ in an injury-riddled stint in Triple-A in 2024, so he's shown a good amount of success at the level.
"A dominant player, Jordan Lawlar!"

While the Diamondbacks haven't pulled the trigger yet, they could give Lawlar a trial run at second base until Marte returns. If he's able to perform with the bat, he could take some playing time from Eugenio Suarez or Lourdes Gurriel Jr. once Marte returns.
Suarez has been ice cold since his incredible first week, and his wRC+ has dropped below 100. Gurriel has been struggling the whole season and has a 29 wRC+.
Whenever Lawlar gets an opportunity to play regularly in the majors, he should provide five-category production. His upside this season is a low-end starting shortstop or a solid option for your middle infield spot if he can secure regular playing time.
